United States Patent 3,253,763 CROSS PARTITION William S. Henderson,Monroe, Mich., assignor to Consolidated Packaging Corporation, Monroe,Mich., a corporation of Michigan Filed Jan. 20, 1964, Ser. No. 338,730 2Claims. (Cl. 229-15) This invention relates to carton partitions andmore particularly to an improved cross partition for the interior of acarton which serves to define article receiving and separating pocketstherefor.

An object of the present invention is to provide an economical partitionor spacer which may be made of inexpensive material easily and quicklyproduced by a low cost process on inexpensive machinery.

Another object of the invention is to produce a collapsible multipartpartition from a single blank of material subsequently separated intoits several parts.

Another object of the invention is to provide a partition for dividing acarton into a plurality of sections or compartments including, forexample, four compartments of substantially equal size.

Generally speaking the partition comprises at least two pair of panelsformed from a single sheet of paperboard,

such as a rectangular or square blank, which is cut, scored,

each section is bent along its intermediate or center line,

such as at a'right angle, to form the separate panels, the tabs of onesection will be secured to the opposite section and the partition willassume the shapeof a cross.

The above mentioned and other features and objects of this invention andthe manner of attaining them will become more apparent and the inventionitself will be understood best by reference to the following descriptionof an embodiment of the invention taken in conjunction with theaccompanying drawing, wherein:

FIG. 1 is a plan view of a rectangular blank scored, cut and providedwith a glue strip to produce the partition of the present invention;

FIG. 2 is a plan view of the blank of FIG. 1 collapsed or folded backupon itself with the glue tabs of each section secured to the oppositesection;

FIG. 3 is a top plan view of the erected partition in a square carton todivide the same into equal parts;

FIG. 4 is a fragmentary perspective view of the erected partition;

FIG. 5 is a sectional detail view taken substantially on line VV of FIG.2 but with the sections spread;

FIG. 6 is a sectional detail view similar to FIG. 5 but on line VIVI ofFIG. 2; and

FIG. 7 is an end view of the collapsed, folded and glued blank of FIG. 2illustrating one means for severing the same into two parts forsubsequent erection.

Referring to the drawings, and particularly to FIGS. 1 and 2 thereof,the partition or divider 15 shown in FIGS. 3-tand 4 may be made from arectangular blank 20 of fibrous sheet material, such as paperboard. Theblank 20 may be scored and cut as shown in FIG. 1, including a cut ortear score or line of perforations 22 between the longitudinal edges ofthe blank such as along the center line, which line 22 is preferablymore cut than connected and also serves as a fold line for dividing theblank 20 into two panel sections or panel pairs 24 and 26. Between thelongitudinal edges of section 24 or outwardly from perforated line 22,there may be provided alternate fold 3,253,763 Patented May .31, 1966scores 28 and cuts 30, the cuts 30 being disposed to one side of theline of the fold scores 28, as illustrated. Section 26 is also providedbetween its longitudinal edges with alternate scores 36 and cuts 38, thecuts 38 being arranged on the opposite side of the line of the scores 36in section 26 from the cuts 30 in section 24.

Cuts 30 comprise spaced longitudinal portions 32 from which obtuseangular divergent portions 34 extend toward and connect with scores 28.Cuts 38 may also include spaced longitudinal portions 40 at the oppositeends of which are opposed V-shaped portions 42 one leg 43 of each ofwhich terminates at the scores 36, which legs 43 also match with theangularity of divergent cuts 34 of cuts 30 when sections 24 and 26 arefolded together along perforated line 22 as shown in FIG. 2. By makingthese cuts 34, 42 and 43 at obtuse angles instead of perpendicular tothe score lines 28 and 36, the releasing and nesting of the tabs 46 and47 are facilitated in setting up or collapsing the partition 15.

Prior to folding the sections 24 and 26 together, as in FIG. 2, anadhesive 45 may be applied-along the alternate scores and cuts of eitheror both sections 24 or 26, as shown in FIGS. 1 and 2, such adhesive 45being applied along a strip not wider than the width of the tabs 46 or47 formed by the cuts 30 or 38, respectively. Due to the alternatearrangement of the scores 28 and cuts 30 in sections 24 and the scores36 and cuts 38 in section 26, the tabs 46 will overlap the scores 36 andtabs 47 will overlap the scores 28 when the sections 24 and 26 overlieeach other as shown in FIG. 2. Accordingly, tabs 46 of section 24 willbe secured to section 26 and tabs 47 will be secured to section 24 alongglue strip 45.

The scores 28 and 36 also serve as fold lines forming a median linealong which not only are sections 24 and 26 secured together, but alsopermits each section to form an angle such as a right angle by bendingthe adjacent panels outwardly which forms a partition of generallycross-shape as particularly shown in FIGS. 3, 4, 5 and 6. Such apartition may be used to divide an elongated carton 50 into four equalsections, which sections may serve to separate stacks of ice-cream conesor paper cups, for example. Such an arrangement provides a plurality ofpockets in carton 50 for preventing contact between and resultant damageto such or other fragile articles.

In producing the collapsed cross-partition of this invention, the blankwith the cuts and score lines can be formed in one operation, then acontinuous strip of adhesive 45 may be applied thereto and the panelpairs 24 and 26 folded together ready for shipment, the perforated oralternate cut and spaced line 22 being such that it can be severed ortorn apart easily upon assembly by the consumer. Preferably, however,the sections 24 and 26 are separated along line 22 in the gluing andfolding machine by means of a knife or sword means 52 such as shown inFIG. 7.

While there is described above the principles of this invention inconnection with specific apparatus, it is to be clearly understood thatthis description is made only by Way of example and not as a limitationto the scope of this invention.

What is claimed is:

1. A partition for dividing a carton into a plurality of sections, saidpartition being formed from a rectangular blank divided longitudinallyinto two sections by a perforated score line, each section being furtherprovided with intermediate longitudinal alternate cuts and scoresforming spaced and staggered glue tabs, and means to secure the tabs ofeach section to the opposite section so that by separating said sectionsalong said perforated score line and bending each section at an angle across partition is produced.

2. A method of making from a sheet of fibrous material a multi-panelcross partition for a carton to divide said carton into at least fourparts, the steps comprising:

(a) cutting a rectangular blank as long as said parti tion and aswide asall four panels of said partition,

(c) alternately scoring and oflE-set cutting tabs along a line betweenthe side edges of each of said panel pairs to define said panels, saidscoring on one panel pair being directly opposite the off-set cuttingson the other panelpair, said ofi-set cuttings forming flaps,

(e) folding said panel pairs together along said perforated line toadhere all of said flaps to a portion of an adjacent panel,

(f) separating the adjacent panels along said perforated line, and

(g) folding said panel pairs along their score lines to separate saidpanels to form said cross-partition with "the central axis of saidpartition along said folds.

(d) applying adhesive along and between said flaps on 15 FRKNKLIN T.GARRETT, Primary Examiner.
